'- PE'D AL AND PEDAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 630,463, dated August 8, 1899. Application filed February 17,1898. Serial No. 670,652. (No modeLl To colt whom, it may concern:

Be it known that LMARMADUKE MATTHEWS,

of the village of Bracondale, in the county of York and Province of Ontario, Canada, have a specification. p

My invention relates to certain improvements in a pedal described in my application, Serial No. 602,882, filed August 12, 1896, and has for itsobject to make the pedal stronger, neater, and adjustable in width and to provide it with a simple and efiicient bearing and a secure lock for the bearing adjustment.

With this object in View my invention consists of a pedal-spindle and acasing formed in two parts screwed together, so that theballbearings between the casin g and spindle may be adjusted by adjusting the casing, which may be held as moved by the pedal-plate. The pedal is formed of a metal plate bent to form a rearward flange, two sides and forward flanges or gripping-pieces, which form a toeclip. The sides of the pedal are held together and are shaped to engage the casing, sub: stantially as hereinafter more specifically de: scribed and then definitely claimed.

Figure l is a perspective view of my improved pedal and bearing. Fig. 2 is a cross-' section of the same provided with rubber treads. Fig. 3 isa longitudinal section of the bearing. Fig. at is an elevation of the spindle, showing the inner half of the'casing slid back to enable the balls to be put in position.

figures.

A is the pedal-spindle, which may be connected to the crank in any suitable manner. Upon this spindle are formed the cones B and O.

The casing of the .bearing is formed in two parts D and E, which are screwed together centrally, as shown at (1. Upon the parts of the casing are formed the cups F and G,which form, with the cones B and O, recesses for two sets of balls, as shown.

From the construction shown it is evident that by revolving one part of the casing with regard to the other the bearings may be accurately adjusted.

In order to lock the bearing, I may use any desired means. I prefer, however, to lock the parts with the aid of the pedal, as hereinafter described.

It will be observed on reference to Figs. 3 and 4 that the least diameter of the part D of the casing is made greater than the greatest diameter of either of the cones or the body of the spindle. Thus the part D of the casing may be slipped into position over the outer end of the spindle while the latter is still secured to .the crank. It may also be slid backward, as shown in Fig. 4:, so that the balls may he slipped into position upon the cone B. The inner diameter of the part E of the casing is of course greater than any portion of the body of the spindle, though the cone end may be of any shape or construction desired to completethe ball-race at that end of the bearing.

It will be observed that the construction and the proportion of parts I have adopted enable me to make a complete bearing in three pieces, which has not heretofore been accomplished. V I

In Figs. 1 and 2 the construction of the pedal is clearly shown. It consistsof the plate I, bent to form a rearward flange or crossbar J, two sides K, and outwardlyturned foot-rests L at the outer end of each side piece, and a flange or gripping-piece M at the outer side of each foot-rest. Immediately below the foot-rest L, I connect the two sides of the pedal by means of a cross-bar or bolt N, provided with a nut 19, so that it will hold the sides of the pedal from spreading. Nuts or collars c are also preferably provided on the cross-bar on the inner side of the sides of the pedal, so as to hold the said sides from being pressed together. A similar cross-bar Fig. 1, and thus securely hold the parts of the casing from turning upon one another. At the same time a firm support is afiorded the pedal. each polygonal portion at is a shoulder 6, against whichthe sides of the pedal are securely tightened by the cross-bars N and O. Instead'offormingthe polygonal portions d of an" integral portion of the parts of the casing g I ma'yusea separate Washer f. (See Fig. 8-.) The end' of the casing is in this case turned round, with a fiat side at one portion of its periphery. The polygonal washer f has a similarly-shaped hole formed therein and is provided with a shoulder g, against which the sides of the pedal will press to retain it in position.

In Fig. 9, instead of using the complete washer f shown in Fig. 8 I use a key f, and in this Fig. 9 the casing is shown round,-but with a flattened side, and the frame K is shownwith an octagonal hole in dotted lines, so-that the casing touches each side of the octagonal openingexcept where the casingis flattened, and between this flattened portion of the casing and that one of the octagonal sides of saidopening with which the flattened portion coincides the said key f is inserted, and the two parts; are-thus held together. Of course it-is' easily seen that if the hearing has to be adj usted the key is taken out and the parts rotated withrespect to each other and the key again-inserted. This key f is th us the equivalent of the washer shown in Fig. 8, although it merely engages withone sideof the opening instead of all of them.

It should be observed that when I use the word polygonal I intend it to refer to regula-r serrations ofany shape. It is also evident that the casing need not be madewith completely'polygonal portions.- (See Fig. 9.) All that is'essential is that the sides andcasing be so shaped that they will engage with oneanother in a number of different positions to permit of and securethe adjustment of thecasin g. I

InFig; 2 it will 'be seen that the'grippingpieceslVI are farther from the spindle'A than the rearward flange J, so that they will grip the select the foot toward the toe, and thus act as a toe-clip. In order to balance the pedal, it is so constructed that the greater portion of the metal therein is below the center ofthe' spindle and at the sametime the-rearward flange is made deep to increase the weight of the metal to the rear of thespindle'.

It will be noticed that behind v vFrom this constructionand proportion of the parts the pedal-when not-engaged with the riders foot lies with a forward and upward inclination ready to be engaged by the riders foot. In this Fig. 2 it will further be noticed that I- have provided the rearward flange J I with a rubber treadP, securely bolted thereto. A piece of rubber tubing Q is placed upon the cross-bar N to .serve a similar purpose. As the cross-bar thus serves for the foot to rest upon, the foot-rests L are not essential, though the gripping-pieces M are still necesj sary to retain the foot in position.

In Figs. 5 and 6 my bearing is shown as 1 used in the pedal described'in the application above referred to. As' shown, the parts of the casing are clamped between the plates I-I- and I, and thus held securely asadjusted. In Fig. 7 I show the bearing asarranged to be tightened by unscrewing one part of the casing from theother, Whereas-in Fig; 3' the bearing is tightened by screwing'one partof the casing upon the other. In this-figurethe cones B and O upon the spindle fac'einwardly instead of outwardly toward the ends and the i cups F and G face outwardly. The polygonal lportions d' of the casing are shown so arranged that the sides of the pedal are placed 1 upon them from the inside instead of from the'outside, as shown-in Figs. 1 and 3. This construction necessitatesone of the cones being made removable. The cone B is bored and counter-bored to receivethe shouldered end of the spindleA. The'end of this spindle is split at j andex panded by means of a small screw it, sofasto securely jam the' cone and spindle together, the bore of the cone being 1 slightly tightened at the end. It' will be observed that the-principle of operation in this construction is the same'in that the adjust ment is effected by screwing'the' parts of the divided casing upon one another, which-parts are held as adjusted by means of the side pieces of the pedal; When it is desired toadjustthe bearing, the c'ross-ba'rsholding. the sides of the pedal together are loosened" and one of the sides spring from engagement with its half of the casing, which may thenbe revolvedto adjust the-bearing, after which the pedal side and easing are again engaged in a= newposi-tion and the cross-bars again secured;

What I claim as my invention is l. Ina pedal, a pl'ate'bent'toforma rearward flange, twosides for attachment toacasing, two outwardly-turned foot-rests at the forward ends of the sides, and a-fl'an'ge at the side of each foot-rest, substantially asand for the purpose specified.

2. In a pedal, a plate bent-to form a rearward flange, two sides for attachmenttoa casing, two outwardly-turned foot-rests at the forward endsof the sides and a" flange at the sideof each foot-rest, in combination with a cross-bar extending from side't'o side of the pedal and provided with nuts whereby'the sides of the pedal may be adjusted closer together or farther apart, substantially as and for the purpose specified.

3. In a pedal, a plate bent to form a rearward flange, two sides for attachment to a casing, two outwardly-turned foot-rests at the forward ends of the sides, and a flange at the side of each foot-rest, in combination with a cross-bar adjustably secured to each side of the pedal near the front, and a cross-bar adj ustably secured to each side of the pedal toward the rear whereby the said sides of the pedal may be spread for adjustment, substantially as and for the purpose specified.

4. In a pedal, a spindle, acasing formed in two parts screwed together, ball-bearings located between each part of the casing and the spindle, so that by screwing or unscrewing the said parts, the bearings may be adjusted, in combination with a pedal-frame adapted to engage the two parts of the casing to hold them from rotating, the said frame being constructed and arranged to spread apart and release said two parts, whereby the latter may be adjusted, substantially as and for the purpose specified.

5. In a pedal, a spindle, a casing formed in two parts screwed together, and ball-bearings located between each part of the casing and the spindle, so that by screwing or unscrewing the said parts, the bearings may be adj usted, in combination with a pedal having two sides so connected that they may be released and spread apart and provided with holes adapted to fit removably upon portions of the halves of the aforesaid casing, the parts being shaped to engage with one another in a number of different positions, and provided with means for preventing the said sides from rotating on the parts of said casing, substantially as and for the purpose specified.

6. In apedal, a spindle; a casing formed in two parts screwed together, and each provided with a portion adapted to engage a suitably-shaped hole in the side of the pedal, and backed by a shoulder; and ball-bearings between each part of the casing and the spindle, in combination with a pedal comprising a rearward flange or cross-bar and two side pieces provided with holes adapted to engage the portions of the halves of the aforesaid casing in a number of different positions; and a removable or releasable cross-bar connecting the said sides, substantially as and for the purpose specified.

7. In a pedal, the combination of a spindle provided with two cones facing the ends of the spindle, a casing formed in two parts screwed together, each part being formed with a cup to complete with the said cones, races for two sets of balls, the inner or crank side of said casing being larger than and screwed on the outside of its companion part whereby the said spindle may be made larger and heavier at its inner end, and a pedal-frame locking said parts when adjusted, the said two-part casing and pedal-frame being constructed to positively engage with each other to form the locking parts, substantially as described.
